To all whom it may concern:

'Be itknown that LPmrnnJosiiBouormn,

a subject of the K-ing'of Great"Britain-"and t Ireland, residing-i at 132*Lots"road,- Chelsea,

London, England, have invented new and usefukMachines forSealingRe'ceptacles; of which the following'is a specification.

This invention relates to improvements in chucks for machines for hermetically lq'sealing :by an externally disp'osed capwfcm lid jars, bottles the like used for: preserves,

jams, and the"like;;in*which means*areflprovided' for automatically setting upa press- 1 ing and rolling'action evenly armune the outside of the metal band'securing"cap or lid, or 'metal'capas mayvbe, so as to grip the underside of the coll'afofflange of the jar, bottle or the like and moreparticiilarly in cases where thetopp'art of-thef-jar or receptacle is not exactly 'circu'larg arid consists in an improved construction whereby ;in addition to theabove," effectivesealing of "the jar or receptacle is obtained when th'p lane of the face of the mouthvof the said jar or receptacle is not exactly at right angles to I the axis of the body thereof, by the provision of a universally mounted holder the chuck being also provided with adjustable means to allow of sealing jars or receptacles with flanges of difierent thicknesses.

In order that the invention may be the better understood I will now proceed to describe the same in relation to the accompanying drawing, reference being had to the letters and figures marked thereon. Like letters refer to like parts in the various figures, in which Figure 1 represents the side of the machine, part being in section and part in elevation.

Fig. 2 is a front elevation of the same.

Fig. 3 is a plan of the chuck disassociated from the machine showing, the operating means for the sealing cones.

Fig. 4 shows a bottle neck associated with the sealing cones, the left handv cone being in the inoperative position during which the bottle neck is raised into position, and the ri ht hand cone being shown in position for e ecting the pressing and rolling operation.

Fig. 5 shows a bottle neck associated with the sealing cones, and illustrates the manner in wh1ch said cones accommodate themselves to variations due to irregularities in 55 the shape of the receptacles being capped.

The working parts are mounted on a cast -"iron frame or stand a with'fa'st and loose pulleys? a -"and' be'Velsgearsa the latter beii-1' keyedto their"respective-shaftsa and a.

- 'The jar or receptacle to'be sealed isplaced 'with-=metal band "or; cap in positi'on on the lifting platform 6 adapted with means for raising or lowering-to "suit-"the "height of jar -*or"*receptacle,-" such= for: examplefasan adjustable collar 0 with set screws of so "that thezf j arf"i'orreceptacle will *pass under, and iclear the rotatinge parts: prior fto" sealing. The jfar orreceptacle"isithen' raised and held in? position' byi placing-"the foot on foot "lei-vendiand' pressing sit-'downward,-said lever beingfelastically held by "means" of" a spring "6. "As the "action is taking placefthe cap enters the 'liolderfffwhich"1s connected to the 'vertical*- PSha-ft a .by means of a---screwed shank f order-that the relative position "offthe holder-f tothe sealing coneso"; may be 'modified to deal with flanges of different thicknesses; The lii'ottomend of the screwed shank f has a swiveling ball-joint r to allow the holder 1 to adapt itself to whatever angle the plane of the top of the said jar may be to its axis.

Levers g are pivoted on the frame at and connected with them is the ring it which is held in the upward position by the spring Links is, of which there are three shown in the drawing, are loosely pivoted at one end to the ring h, and at the other end to the knuckles Z. The knuckles Z are loosely pivoted in one end of the levers n which in turn are pivoted on the chuck m, while the other end of the levers n carry the vertical stems s carrying the sealing cones o the said stems being disposed in slots 0 in the chuck m. When the ring it is moved downward by the lever g the cones 0 travel toward the center of the chuck m and vice versa. The cones 0 are preferably fitted with ball bearings on their stems s for easy turning, the ball bearings being slidingly arranged on the said stem 8; rubber buflfers 0 being provided to allow limited vertical movement of the cones 0 in order that compensation for the irregularities of the neck or flange of the jar may be provided for.

When the various parts are in position and at the correct height for the particular receptacle to be sealed the belt is first shifted from the loose to the fast pulley, thereby rotating the vertical shaft a and chuck m carrying the cones 0, then by means of the lever g, the sealing cones o are brought in-- Wardly into intimate contact with the edge of the metal cover surrounding the lip of jar or receptacle in sucha Waythat lateral andvertical compression forces are impressed on the metal so as to roll it inwardly under the lower edge of the lip ofthe jar or receptacle thus securing the metal band or cover in place. v 'v v' The stems s carrying the sealing cones 0 can alternatively be made With long bearings and have springs fitted below the cones 0 to permit the said cones 0 to accommodate themselves to variations due to the jars or receptacles being irregular in shape and out of true as hereinbefore described.

Plates 9 are provided for keeping the jar or receptacle in position on the platform I).

I claim: c '1. Apparatus for applying sealing bands to capped receptacles and the likeconsisting of, in combination, a revolving chuck, a cap support universally mounted therein and adapted to remain stationary While the said chuck" is revolving, a'series of stems depending from said chuck and adapted to have a movement to and from the axis of said chuck, means'for operating said stems, a seallng cone freely mounted on each of said stems so as to both revolve and slide axially Copies of thispatent may be obtained for thereon and an elastic device on each stem adapted to press the said cone in a direction toward the portion of the band to be beaded over, substantially as described. 7

2. Apparatus for applying sealing bands to capped receptacles and the like consisting of, in combination, a revolving chuck, a cap 1 support universally mounted therein and "on and an elastic device on each stem adapted to press the said cone'in a direction toward the portion of the band to be beaded over, substantially as described.

In Witness whereof I- have signed my name to this specification in the presence of tWo subscribing Witnesses. I
